SHUTTLE Specification of Letters Patent.

Patented Jan. '7, 1908.

Application fi rch 6. 1906- Serial No. 304.444.

To all whom it may concern:

Be it known that I, GIUsEPPn PAVIA, a subject of the King of Italy, residing in- Allentown, county of Lehigh, State of Pennsylvania, have invented certain new and useful Improvements in Shuttles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

My invention is an improvement in shuttles for looms weaving broad goods, and it relates particularly to the construction of the bobbin skewer or spindle and its accessory the usual lug 9 adapted to take up parts. In shuttles of this kind at present in use, the pivoted skewer or spindle is iminged against on an angular face thereof by a bent plate-spring held in position by several pins mounted in the walls of the shuttle and traversing the bobbin chamber near one end thereof.

My objects, among others, are to reduce the expense of materials and labor incident to the manufacture of shuttles with respect to the parts above referred to and to so construct and arrange the same as to avoid any possibility of splitting the shuttle, as is now sometimes the case in the use of the s ring aforesaid, and insure against the shutt e being placed in the loom with the skewer not fully depressed, as also sometimes now occurs when the parts become worn or weak.

I have illustrated my invention in two views in the accompanying drawings, wherein,

Figure '1 is a plan view of the improved shuttle; and Fig. 2 is a side view thereof, showing the near wall partly broken away.

a is the shuttle, 1) its bobbin chamber, and c the usual bobbin-skewer or spindle; (Z is the bobbin or cop arranged on said skewer.

The body or pivot part c of the spindle or skewer c is fulcrumed on the pivot pin {which traverses the bobbin-chamber I), and it has against a shoulder h in the bottom of said chamber when the spindle is in its proper depressed position in the shuttle. On one side of said body or pivot part 0 (preferably the top side) is formed a lug i; otherwise this side is or may be substantially flat.

j'is a recess forming an extension of the bobbin-cha1nber and disposed longitudinally at the pivot end of the skewer. In this recess is arranged a catch 0 extending longitudinally of the shuttle 'and preferably in the form of a lever fulcrumed between its ends on a pin 7c which traverses the recess. The inner end of this catch bears against the body or pivot part c of the skewer and it is formed with a notch Z adapted to receive the lug i of said body or ivot part when the skewer is in the depressed position, as shown, at which time it holds the skewer positively against movement on its pivot. Under the outer end of said catch is a coiled spring m set in a socket n in the bottom of the recess and acting to press the said outer end of the catch upwardly, whereby to preserve contact between the catch and the body or pivot part c.

In order to raise the spindle or skewer, the outer end of the catch is depressed by the finger until the lug i and notch Z clear each other. WV hen the skewer or spindle is depressed, the spring causes the catch to snap into position, bearing squarely against the top face of the body or pivot part c, as soon as the lug and notch coincide with each other, in which position the skewer will be locked firmly in the depressed position.

Having thus fully described my invention what I claim as new and desire to secure by Letters Patent is:

The combination of a shuttle body having a bobbin chamber and a recess forming a longitudinal extension of said chamber and opening upwardly through the top of said shuttle body, a bobbin spindle fulcrumed in said body, a substantially horizontal catch fulcrumcd between its ends in said recess and having one end bearing on the butt or the spindle, the material of the shuttle body being extended intact under said recess and thus forming the bottom wall of said recess and being formed with a shoulder having one face at right angles to the closed position of the spindle, and a spring interposed between the other end of the said catch and the bottom wall of said recess,

spindle having the one a lug and the other a said catch and the notch engageable With each other to lock the have hereunto set my hand this 3rd day of spingle 1against pivotal moYement and slaid March, 1906. s in e avin a ownward ro'ectin u' a dapted to en gage said fac hi th e sho lde?

substantially as described. 7 JOHN W. STEWARD, In testimony that I claim the foregoing, I OESARE OASARIOO.
